A roller cam is used to impart a periodic motion to the base of the spring-mass system shown in Fig. 4.41. If the coefficient of friction between the mass and the surface is µ find the response of the system using the principle of superposition. Discuss the validity of the result.
Consider the flow of a uniform stream of speed V in the x-direction and a sink of strength Q at the origin. Find the stagnation point(s) and the equation of the stagnation streamline. Sketch (freehand) the flow streamlines
Consider a very ductile material that begins to neck in tension at a true strain of 0.20. Necking causes an additional elongation that is approximately equal to the bar diameter.

Determine the likely power developed by the turbine, the specific speed and specific diameter, and the most suitable type of turbine for this duty.
A 7in diameter cylindrical scuba tank made from steel is being designed for an internal pressure of 1600 psi. The allowable stress of the steel is 35 ksi in tension and 16 ksi in shear. Calculate the minimum wall thickness assuming a factor of safety..
The stators in a gas turbine are designed to increase the kinetic energy of the gas passing through them adiabatically. Air enters a set of these nossels at 270 psia and 795 F with a velocity of 97 ft/s and exists at 200 psia and 550 F. Calculate the..
